In 1959, ground was broken, and in 1961, the foundation of the structure was laid. Construction of the arch itself began on February 12, 1963, as the first steel triangle on the south leg was eased into place. These steel triangles, which narrowed as they spiraled to the top, were raised into place by a group of cranes and derricks. The arch was assembled of 142 12-foot-long (3.7 m) prefabricated stainless steel sections. Once in place, each section had its double-walled skin filled with concrete, prestressed with 252 tension bars. In order to keep the partially completed legs steady, a scissors truss was placed between them at 530 feet (160 m), later removed as the derricks were taken down.
Both the width and height of the arch are 630 feet (192 m). The arch is the tallest memorial in the United States and the tallest stainless steel monument in the world. The cross-sections of the arch's legs are equilateral triangles, narrowing from 54 feet (16 m) per side at the bases to 17 feet (5.2 m) per side at the top. Each wall consists of a stainless steel skin covering a sandwich of two carbon-steel walls with reinforced concrete in the middle from ground level to 300 feet (91 m), with carbon steel to the peak. The arch is hollow to accommodate a unique tram system that takes visitors to an observation deck at the top. The structural load is supported by a stressed-skin design. ] Each leg is embedded in 25,980 short tons (23,570 t) of concrete 44 feet (13 m) thick[57] and 60 feet (18 m) deep. Twenty feet of the foundation is in bedrock. The arch is resistant to earthquakes and is designed to sway up to 9 inches (23 cm) in either direction while withstanding winds up to 150 miles per hour (240 km/h

Janette, how kind! I just finished thanking Christina for featuring your unforgettable "Dachsy" when your comment appeared. Here you've served up: our kids' favorite (the St Louis Arch), & my favorite (a ballpark) as dessert... who could ask for anything more?
Janette Boyd replied:
Joseph, I appreciate your comment on this image! I loved that landmark so much. I was really surprised that this picture came out and I was very pleased. I have another image of the stadium by itself that is under the "Sold" gallery if you wanted to look at it. Thank you so much for your nice comments!!

This is a great shot! When I lived here I never went up. We never appreciate the things we should, I guess. LF
